A fusion torch is a technique for utilizing the high-temperature plasma of a fusion reactor to break apart other materials (especially waste materials) and convert them into a few reusable and saleable elements.
A plasma torch cutter. A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. [1] [2] [3] The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. [4]
CNC plasma cutting Plasma cutting performed by an industrial robot Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma . Typical materials cut with a plasma torch include steel , stainless steel , aluminum , brass and copper , although other conductive metals may be cut as ...
The high temperature of the plasma allows the atomization of molecules and thus determination of many elements, and in addition, for about 60 elements the degree of ionization in the torch exceeds 90%. The ICP torch consumes c. 1250–1550 W of power, and this depends on the element composition of the sample (due to different ionization energies).
The tiny droplets are spherical and measure between 50 and 350 μm. The TGA process has been used to produce a wide variety of materials such as commercially pure (CP) titanium, conventional alpha-beta and beta alloys. [5] In plasma atomization (PA) process, a titanium wire is atomized by 3 inert gas plasma jets to form spherical metal powders.
The plasma can reach temperatures up to 10,000 Kelvin. Inductive plasma technology is used in fields such as powder spheroidization and nano-material synthesis. The technology is applied via an Induction plasma torch, which consists of three basic elements: the induction coil, a confinement chamber, and a torch head, or gas distributor.

Schematic of VAR apparatus. The alloy to undergo VAR is formed into a cylinder typically by vacuum induction melting (VIM) or ladle refining (airmelt). This cylinder, referred to as an electrode is then put into a large cylindrical enclosed crucible and brought to a metallurgical vacuum (0.001–0.1 mmHg or 0.1–13.3 Pa).
